I ordered 8 new control knobs for my cooker and they were the wrong ones, went on the website to the "help and advice " section which is useless. I cannot get the answer to find out what I need to order because the website says " no order found" and I just get referred back to a link to the website. I am now returning them in the same envelope as they came in the hopes that I get my money back and find another company to deal with
